Citadel Sinocore Panel System

Citadel SinoCore®

panel20battenmockupbig SinoCore® is a composite panel made by laminating either textured or smooth prefinished aluminum skins to a core of high density polypropylene.A second aluminum skin is added as a backer and provides panel balance.

Panels are furnished with a strippable film (or interleafed microfoam) on the painted surfaces to protect the finish during shipment and installation. SinoCore® is attached to the substrate using either mechanical fasteners or construction adhesive, depending upon the method selected. Joints are finished using one piece or two piece extruded aluminum trim moldings.

As an alternative or complement to other exterior building finishes such as stucco or brick, SinoCore® is designed for applications such as:claddings, fascias, canopies, and accent bands. SinoCore® is typically used on low and medium rise buildings such as schools, banks, office parks, medical facilities, etc… However, with a variety of finish options, SinoCore® also adds aesthetic interest to otherwise monolithic structures (i.e. preformed warehouse walls).

As a complete exterior cladding system, SinoCore® offers a number of benefits to the building owner, architect, and installer including:

  • Lightweight
    With an innovative polypropylene core, SinoCore® is lightweight making it easier to handle, cut in-the-field, and install.
  • Easy Installation
    Simple sheets/trim concept easy to understand. Standard carpentry knowledge and tooling is all that is required for installation.
  • Curveable
    While tight radius requirements are not recommended with SinoCore®, panels can be gently curved in-the-field to achieve graceful lines.
  • Color Matched Moldings
    Several different profiles available to complete the system look. Moldings are painted to color match or complement panels.
  • Versatile
    With textured or smooth skins available, SinoCore® can provide a number of different looks for your project including metallic and anodized finishes.
  • Water Resistant
    Virtually unaffected by water, SinoCore® provides an attractive alternative for situations where moisture is a primary concern.

SinoCore® is intended for use as a lightweight exterior cladding. It should not be used in low grade
areas where panels are exposed to high traffic and/or heavy abuse. It cannot be considered as a structural element of a wall assembly.

SinoCore® panels are available with either smooth or textured prefinished aluminum skins. Standard colors in textured skins are offered with a coil coated polyester. Panels can also be ordered in premium colors with an acrylic urethane coating. Smooth standard and metallic colors are furnished with a Kynar 500® coating. Anodized finishes are available as a standard finish. Custom colors are also available. Moldings are coated using a polyester, acrylic urethane or Kynar 500® paint system depending upon the panel finish and can be painted to match any standard or custom color.



For a non-progressive installation, the two piece extruded moldings may be used. Plastic receivers are first installed, then construction adhesive is placed in the field of the panel. The panels are then fastened around the perimeter and sealant is applied. The joints are completed with a snap-on aluminum cover.

For a progressive installation, the one piece moldings are used. The extrusions are mechanically fastened to the substrate and the panels are then installed using sealant at the perimeter and construction adhesive in the field of the panel.
